On possibility is that the lack of webcam on the iPad is largely due to bandwidth limitations for the 3G model. In other words, the idea is to keep the AT&T networks from melting. Obviously a camera isn't expensive nor does it take up much room, so I have a tough time imagining that's the limitation.
Um...no. Every cell phone from the most advanced (iPhone) to the simplest flip phone has a camera. Even 3G netbooks have cameras. Bandwith limitations for video conferencing don't make sense either, since we're not necessarily speaking of a front facing camera, just a camera in general (anywhere on the device). Also, not putting in a camera due to the expense or concerns for room are not it either.
Simply put, Apple is saving features to "add" to the next version to give people a reason to upgrade, I guess. Who knows why Apple does what it does? I can tell you this much, I believe they really dropped the ball on this one. They had the chance to really make a big splash and create a market for a product that could have been revolutionary. They were so close. I really believe if they would've added just two elements to the iPad, just two, people perceptions of the unit would be much more positive and reviewers wouldn't be writing the "it's just an overgrown iPod Touch" articles everyday.
The first element is a camera. The second is multitasking. Obviously multitasking can always be added via an OS upgrade, but for Apple to release this new product without a major revision of the iPhone OS was a HUGE mistake. I spoke with a developer who was tweaking his app on the new tools provided in the new SDK, and he said the app just looked kind of silly just floating in its original size in the middle of the huge screen, and it didn't look much better doubling the pixels. With the new screen real estate, how cool would it have been to allow multiple apps to be on the screen at once, running, in effect, like widgets. There's your magic. That's your revolutionary device. Listen, I love everything else about it, but these two major omissions change everything. The average consumer may not be able to know what's missing, he or she just knows it's missing something. Which leads to the "it's just a big iPhone" perception. 60 more days of negative press and negative word of mouth before anyone can get their hands on one won't help either.
Apple, you were so close, but you blew it.
